Puipuiga Fa'alelalolagi
Directional earth fault, for ring networks and parallel feeders.
I2>ANSI 46
Puipuiga o le so'o o le aave vaega leaga
Detects unbalance, broken conductors and single phasing from the negative-sequence current.
θ>ANSI 49
Puipuiga o le avega
A thermal model of the plant that trips before a cable, transformer or motor overheats.
CBFANSI 50BF
Puipuiga fa'aletonu autu
Trips the upstream breakers when a breaker fails to open after a trip command.
I> ↑CLP
galuega e iloa ai uta malulu (CLP)
Raises the settings for a while after a long-dead feeder is re-energised, avoiding nuisance trips.
I2f / I1fInrush
Inrush galuega su'esu'e i le taimi nei
Recognises transformer inrush from the second harmonic and blocks false trips.
Id>ANSI 87
Puipuiga ese'ese
Compares the currents into and out of the plant and clears faults inside the zone fast.
